THOMAS S. GROMER, OF LINDEN, TEXAS, ASSIGNOR OF ONE-HALF .TO JOHN E. A. BANGER,

OF LINDEN, TEXAS.

COMPOUND BAIL.

To all whom it may concern:

Be it known that I, THOMAS S. CROMER, citizen of the United States, residing at Linden, in the county of Cass and State of Texas, have invented certain new and useful Improvements in Compound Rails, of which the following is a specification.

This invention relates to a railway rail of the composite type and aims to provide an article of this nature which will be as strong at the oint as at any point between the joints and which will provide a tread surface capable of sustaining the load at the joint as at any other point, thereby preventing any jar, noise or shock when the wheels of a car or locomotive engine are passing over the joint. The rail embodies a tread portion and a separable base portion, the two arranged to break joint, the base portion having transversely spaced flanges and the tread portion having a pendent web to fit between the flanges of the base portion, said web being thickened in its length and gradually tapered towards the extremities, and the flanges of the base portion having the spaces between their end portions gradually widened to accommodate the thickened portion of the web of said tread portion,'thelatter also having longitudinal grooves in the underside of its head or ball adjacent to the web to receive the upper edge portions of the base flanges.

The invention will be more particularly set forth hereinafter and indicated in detail in the subjoined claims and is illustrated in the drawings hereto attached, in which:

Figure 1 is a side view of a compound rail embodying the invention. Fig. 2 is a horizontal section of the rail on the line y-g of Fig. 1. Fig. 3 is a transverse section on the line :ra: of Fig. 1. Fig. 4 is a perspective view of the tread portion of the rail inverted.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The base portion 1 of the rail embodies transversely spaced flanges 2 projected upward therefrom along a mutual line and forming an integral part thereof. The space formed between the base flanges 2 is gradually widened at its ends, as shown at 4 to correspond with the thickened portion of the web of the tread portion so as to form Specification of Letters Patent.

a snug joint therewith. The tread portion consists of a head 5 and a web 6, the latter extending from the head on a medial line and forming an integral part thereof. The web 6 is thickened between its ends, as indicated at 7, the thickened portion tapering towards opposite ends of the web in conformity to the flare or taper of the spaces 4 so that when the parts of the rail are assembled, the thicker part 7 of the web 6 will snugly fit adjacent spaces 4; in contiguous ends of base portlons of the rail. Grooves 8 are formed in the underside of the head 5 adjacent to the web 6 and receive the upper edge portions of the base flanges 2, thereby preventing spread or lateral separation of said flanges. Corresponding openings'are formed in the base flanges 2 and in the web 6 and receive the bolts or fastenings 9, by means of which the parts are secured when placed together. The openings in the web 6 are elongated in the direction of the length of the rail to allow for contraction and expansion.

In assembling the parts, the tread portion of the rail is arranged to break joint with the base portion, the thickened portion of the web 6 being arranged opposite the joint formed between adjacent base sections with the result that the tread portion is as strong at the joint as at any point in its length, hence will resist wear and strain and will support the load imposed thereon without producing any susceptible shock or vibration other than that experienced when the rolling stock is moving upon any other port-ion of the rail. It is to be understood that the sections may be of any length and gage and may be constructed in any economical way so as to produce a commercial and practical article.

Having thus described the invention, what is claimed as new is:

1. A compound rail comprising a base portion having transversely spaced flanges, and a tread portion, the latter arranged to break joint with sections of the base portion, said tread portion comprising a head and a web, the latter entering the space between the flanges of the base portion and said Web having a thickened portion between its ends to fill widened spaces formed between the flanges of adjacent base portions.

2. A compound rail consisting of a base ranged to break joint with the former, the v base portion having transversely spaced flanges, the space between said flanges gradually widening at opposite ends and the tread portion comprising a head and a web, the latter being thickened between its ends and tapered outward to snugly fit the enlarged end portions of the spaces formed between the flanges of adjacent base portions, and said head having grooves in its underside adjacent to the web to receive the upper edge portions of the flanges of the base portions.

In testimony whereof I affix my signature in presence of two witnesses.
